WILLIAM OARDYVELL, OF ST. JOSEPH, MISSOURI.

WAGON-BRAKE LEVER.

SPECIFICATION forming part of Letters Patent No. 303,264, dated August 12, 1884.

(No model.)

To all whom it may concern:

Be it known that I, W'ILLIAM CARnwnLL, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Wagon-Brakes; and I do hereby declare that the following 'is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a perspective view of my invention, showing it connected to a wagoirbody; Fig. 2, a sectional view' of the pivoted clutch, taken on line a a; of Fig. 3; Fig. 3, a side elevation thereof; Fig. 4, a detail view in perspective of the bearingplato, to which is connected one of the journals of the clutch; and Fig. 5, a cross-section taken through the clutch and lever.

The present invention has relation to certain new and useful improvements in the means for operating the brake-shoes of wagons or other vehicles; and it consists in the details ofeonstruetion, substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanyingdrawings, A represents a portion of a wagon-body, to the under side of which are suitably connected the bearing-plate B and bracket C, said bracket extending out from the side of the wagon-body,

and,togetherwiththeplatel3,for1ninghearings for journals to upon a clutch, D. is formed wedge shape, as shown in Fig. 2,

over which fits the lower end of alever, E,

formed with a wedge-shape bifurcation, I), thus enabling the end of the lever, which is pivoted at etc the clutch, to work thereon without bindmg, and making a more perfect joint without a suitable lever having a blfnrcat on at its the danger of any foreign substance working in between the bifurcated end of the lever and the sides or faces of the clutch.

The clutch I), if preferred, maybe provided with flanges d upon both its sides, to form stops to limit the-motion of the lever with relation to said clutch; but this, however, is not essen tial, and may he used or not, as found desirable.

This clutch 'rods, which are in turn connected to the lever E, and these features forming no part of the invention, it is not considered necessary to illustrate them.

It will be noticed that the pawl G is of suffi cient length to engage with the teeth on the bar F at any point on the arc of a circle described by the lever.

The lever E is connected in such manner by means of the pivoted clutch D as to provide a double joint, thus admitting of the lever having a double n1ot-ion-viz., lengthwise of the bar F and transversely therewith when it is desired to release the pawl from engagement with the teeth of the bar, or, in other words, a longitudinal and lateral play.

It is evident that the bearings for the journals of the clutch may be variously modified or changed, as circumstances require, without departing from the spirit of my invention; and any suitable pawl-and-ratel1et device for holding the lever stationary may besubstituted for the means shown, this also being a feature susceptible to change or modification.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The means, substantially as herein described, for operating the brakes of wagons or other vehicles, consisting of a pivoted clutch,

lower end, extending over the clutch and pivoteil thereto, and a pawl-and-ratchet device for holding the lever stationary, for thepurpose set forth.

2. .Inawagon-brakc,apivoted clutch formed wedge shape, in combination with a bifurcated lever pivoted thereto, and carrying a stirrup and pawl, the latter adapted to engage with a toothed bar connected to the Wztgombody, In testimony thatI claim the above I hzwe substantially as and for the purpose specified. hereunto subscribed my name in the presence 3. In a wagon-brake, a flanged and pivoted of two witnesses. clutch, in combination with a bifurcated lever WVILLIAM OARDVVELL. 5 pivoted. thereto, and a pawl-and-ratchet de- Witn esses Vice for holding the lever stationary, substanl J OHN D.

tially as and for the purpose described.
